Is there some way to get a set of virtual machines which share a tag? #2

There is no filtering option inside the list operations. I suggest you to do it using a list comprehensions:

def tag_is_present(tags_dict):
    return tags_dict and tags_dict.get('mytag') == 'myvalue'
tagged_vms = [vm for vm in compute_client.virtual_machines.list_all() if tag_is_present(vm.tags)]

I am personally of the belief that there should be a filtering method provided by the API, but I agree this represents a viable way of solving this problem. Thanks @lmazuel

@zfrenchee One other possibility is to use the generic list resources, filtering by tag: https://msdn.microsoft.com/en-us/library/azure/dn790569.aspx

You will not get a VirtualMachine object and you might miss some properties: you might want to do a get on the compute client to get them. But at least it will be filtered. Depending of your volume and situation could help.

The generic list with filter readthedocs link.
